In the process of biological research and industrial production, Medium filter membrane is an important experimental and production auxiliary tool. It can effectively remove impurities in cell culture fluid and ensure the normal growth and reproduction of cells. However, how to choose a suitable culture filter membrane?

1. Determine the filtering precision

Need to determine the filtering Accuracy. Different filter membranes have different filtration precisions. Choose the appropriate filtration precision according to your needs. For example, if you need to remove larger particles, you can choose a filter membrane with higher filtration accuracy; if you need to remove smaller particles, you can choose a filter membrane with lower filtration accuracy.

2. Consider material type

Medium filter membrane The main material types include polyester, polyethersulfone, polyvinyl chloride (PVC), etc. Polyester filter membrane has good chemical stability and temperature resistance and is suitable for filtration of most biological liquids; polyethersulfone filter membrane has higher chemical resistance and heat resistance and is suitable for highly corrosive biological liquids. filtration; polyvinyl chloride (PVC) filter membrane is suitable for filtration under high temperature and high pressure. Choose the appropriate material type based on your usage environment and needs.

3. Consider the pore size

The pore size of the filter membrane directly affects the filtration effect. Generally speaking, a filter membrane with a larger pore size can remove more particles, but may affect cell growth; a Medium filter membrane with a smaller pore size can better protect cells, but may affect the growth of cells. Effect. Therefore, when selecting a filter membrane, it is necessary to weigh the effects of filtration efficiency and cell growth and choose an appropriate pore size.

4. Consider price and cost performance

You need to consider the price and cost performance of the filter membrane. The prices of different brands and types of filter membranes vary greatly. When choosing, you need to comprehensively consider the filtration effect, material type, pore size and other factors, as well as your budget, and choose a filter membrane with a higher price ratio.

In short, when selecting Medium filter membrane, factors such as filtration accuracy, material type, pore size and price need to be comprehensively considered. to meet your experimental and production needs.

The currently independently developed tissue culture hydrophobic vapor-permeable membrane is the core material for culture medium filtration. It has high retention rate, high flow rate, low pressure difference and a wide range of chemicals. Compatibility and other features. Interested parties are welcome to enter the store and contact us.
